This application claims priority to U.S. Provisional Patent Application Ser. No. 61/096,985 filed Sep. 15, 2008 entitled “System for Web Site Personalization”, the entire contents of which is incorporated herein by reference.

BACKGROUND

One of the most common activities related to the Internet is searching for information. The search for information is conducted either via dedicated portal web sites, or via search options provided as part of information bearing sites. Typically, the search is conducted by providing one or more key words, and some defined relation between them. One of the common problems of searching is the wealth of information provided. In many cases the user needs to review many items before identifying his desired target information. To resolve this issue the user needs to add additional keywords in order to hone in on his requirements and filter out unwanted information. In parallel, much effort has been devoted to relieve the user of adding keywords by providing various forms of search enhancement. The search enhancement approaches can be broadly separated into two types:

-   -   Semantic search, with the goal of enabling the user to describe         his information needs rather than delving on the mechanics of         keywords.     -   Collaborative filtering approaches, where the user's activities,         interest or reference group are used to hone in on the user's         interests and thus identify the appropriate target information.

Since the results of a search are displayed as a list, a key issue in providing the information to the user is to bring relevant information to the top, or near the top, of the list. The relative location in the list in prior art systems is defined by the rank of the web site in the search engine's ranking system.

Across the chasm of the search engines lies the web pages themselves, organized into a web site. The goal in producing a web site is to reach out to the information seekers and provide the content of the web pages of the web site to the information seeker. Since the connection to the information seeker is facilitated by the search engines, the web sites employ methods broadly termed Search Engine Optimization (SEO) which attempt to enhance the ranking of the web site, and/or web pages thereof, by manipulation and incorporation of keywords into the web site.

Both of the search enhancement approaches, as well as the web site's SEO to enhance their ranking, are based on segmentation of target audience and optimizing keywords based on the segmentation. Unfortunately, the web sites lack a general and direct method of increasing their rank in the search engine for a segmented audience. Increasing the rank for a target audience allows for a more efficient use of resources, and preferably further results in an improved user experience. It is to be noted that privacy concerns must be taken into account, to ensure that identifying information is not made publicly available.

There is thus a long felt need for a method for enabling sites to define their target audience in a way that improves the ranking of search results for that target audience. Preferably, the method directly defines the target audience and does not infer it from heuristics, statistics and/or collaborative filtering.

SUMMARY

Accordingly, it is a principal object of the present invention to overcome at least some of the disadvantages of the prior art. In certain embodiments this is provided by a system comprising a server and a user computing station. Stored on the server is a plurality of attributes, such as: age, gender, profession, residence area, income level and marital status, without limitation. A plurality of values is also stored, with each stored attribute having associated therewith a plurality of values. A user can select, via the user computing station, one or more of the plurality of stored attributes and appropriate values for each selected attribute. The server is arranged to then provide an archetype corresponding to the selected attributes and values, which is in one embodiment stored on the user computing station. In one embodiment the provided archetype does not support unique user identifying information. Preferably, the user is provided with an API, toolbar, or other means of defining, changing, adjusting and tuning of the archetype. In another embodiment the provided archetype is stored on the server.

In one embodiment the system further comprises a network accessible host arranged to retrieve from the server one or more of the plurality of stored attributes, and one or more values for each retrieved attribute. In one embodiment, the network accessible host is arranged to then generate a meta-descriptor for an object stored on the network accessible host, corresponding to the selected attributes and values. In one embodiment the generated meta-descriptor is generated responsive to the content of the object. In one embodiment a plurality of meta-descriptors is stored on the server and the network accessible host is arranged to retrieve from the server a meta-descriptor for an object stored on the network accessible host. In one embodiment the meta-descriptor is attached as a tag to the object. In one embodiment the meta-descriptor can be attached to an existing meta-data tag attached to the object. In one embodiment the attached meta-descriptor is broadcast throughout the network, for example by broadcasting the meta-descriptor through search engines.

In one embodiment, for each generated archetype a single corresponding meta-descriptor is generated. In another embodiment, for each generated archetype a plurality of meta-descriptors are created, each meta-descriptor at least partially corresponding to the generated archetype.

In one embodiment each attribute and value stored on the server has a corresponding code. A user, having defined an archetype, is provided with a code, the provided code being an encoded function of the archetype. For each meta-descriptor a code is similarly provided, the provided meta-descriptor code being an encoded function of the meta-descriptor. When the user performs a search for an object, the codes representing the archetype associated with the user are compared with the codes representing the meta-descriptors attached to the objects stored on the network accessible host. Objects that do not have a meta-descriptor corresponding with the user's archetype are not displayed. In one embodiment the user can choose to search using the above described archetype filtering or to search without the archetype filtering. In one embodiment, wherein the searched for object is a web site, the archetype filtering is done by a search engine. In another embodiment, wherein the searched for object is a web site, the archetype filtering is done by the user's web browser. In yet another embodiment, wherein the searched for object is a file stored in a database, the archetype filtering is done by a program stored on a user computing station.

Additional features and advantages of the invention will become apparent from the following drawings and description.

Memory 60 is in communication with processor 70 and memory 80 is in communication with processor 90. Processor 120 is in communication with each of user input device 100 and memory 110. User input device 100 comprises a keyboard, mouse, touch screen, or any suitable device designed to enable a user to make a selection.

Server 20, network accessible host 30 and network 50 are illustrated as being external to user computing station 40 however this is not meant to be limiting in any way. In one embodiment server 20 is a computer program located on processor 120, as will be described further hereinto below. In another embodiment network accessible host 30 is a database located on memory 110, as will be described further hereinto below. In yet another embodiment network 50 is an operating system running on processor 120, as will be described further hereinto below. Network 50 can be any type of network, including without limitation the Internet, an Intranet or other local area network.

FIG. 2 illustrates a high level functional diagram of memory 60 of server 20 of FIG. 1, comprising: an archetype database 130; a meta-descriptor database 140; an attribute database 150 comprising a plurality of attributes, denoted respectively A1, A2, . . . AN; and a value listing 160 comprising a plurality of attributes V1, V2, . . . VN for each attribute of attribute database 150. For each attribute in attribute database 150, at least one value is provided in value listing 160.

The term values used herein includes any word, or words, defining the different options that exist for each attribute. In one non-limiting example, in which an attribute for age is defined, specific ranges of ages are grouped together. Alternatively, each particular age value is enabled. In another non-limiting example, a list of professions are provided, each pre-defined profession being term a value associated with the attribute profession. In yet another non-limiting example, areas of residence are provided, each pre-defined area of residence being termed a value associated with the attribute residence. Preferably, the pre-defined areas of residence are provided to be sufficiently broad so as not to provide significant identifying information.

FIG. 3 illustrates a high level functional diagram of memory 80 of network accessible host 30 of FIG. 1, comprising a plurality of objects 170, denoted respectively WS1, WS2, WS3, . . . WSN. Optionally, as will be described further hereinto below, for each object 170 a particular meta-descriptor 175 is attached preferably as part of a tag associated with a respective object 170. Each object 170 may be constituted of a web site, a plurality of web sites, one or more web pages, an object, or a plurality of files and/or folders, without limitation.

FIG. 4 illustrates a high level functional diagram of user computing station 40 of FIG. 1, further comprising a web browser 180 and a search engine 190. Web browser 180 and search engine 190 are each in communication with processor 120, and as indicated above in relation to system 10 of FIG. 1, processor 120 is in communication with memory 110.

Search engine 190 is shown as a separate function from web browser 180, however this is not meant to be limiting in any way. Web browser 180 and search engine 190 are illustrated as being stored on computing station 40, however this is not meant to be limiting in any way. In another embodiment web browser 180 and/or search engine 190 are stored external of user computing station 40 and can be accessed through network 50.

For ease of understanding the operation of FIGS. 1-4 will now be described together. In one embodiment, a user searching for information accesses web browser 180 via user input device 100. Web browser 180 provides the user with the option of choosing an existing archetype, preferably stored on one of archetypes database 130 and memory 110, or defining a new archetype. Definition of an archetype, as described further below, is advantageous as it provides a user with a means of characterization without revealing actual personal identifying information.

In the event that the user chooses to define a new archetype, web browser 180 communicates with server 20 and provides the user, via web browser 180, a list of attributes stored in attribute database 150. The list of attributes stored in attribute database 150 comprises, in one non-limiting illustrative example, any of: age, gender, profession, residence area, income level and marital status. Preferably, the list of attributes stored in attribute database 150 does not include unique identifying information, such as, without limitation: name, address and telephone number. The user may select one or more attributes. For each attribute chosen by the user, processor 70 provides the user with a list of pre-determined values associated with the chosen attribute, stored in value listing 160, and the user selects one or more values to be assigned for the archetype. The selected attribute and the respective associated selected value are then added to the user's archetype.

In one embodiment an API, toolbar, extension to a web browser, an integrated web browser, a stand alone program, designated cookies, a web site, or other means are provided on user computing station 40, or accessible via user computing station 40, allowing the user to define, change, adjust and/or tune the generated archetype by accessing server 20. In one non-limiting embodiment, once the archetype is defined only the values associated with the archetype can be viewed by the user, while in another embodiment the attribute descriptors associated with the values can be viewed by the user.

In one non-limiting illustrative example, the viewable archetypes is in the form of:

-   -   age: 40-50     -   engineer, male, likes gadgets     -   profession: student, gender: female, age: 13-16, likes music,         likes rock music

The defined archetype is then stored, in one embodiment, in memory 110 of user computing station 40. In another embodiment, the defined archetype is stored, preferably associated with a user name and password on archetype database 130. In one embodiment the defined archetype is further stored on archetype database 130, as one of the combinations of archetypes which have been defined, for use in developing statistical information regarding defined archetypes and attributes.

In the event that the user selects to utilize an existing archetype, in an embodiment in which defined archetypes are stored in memory 110, the list of stored archetypes are displayed to the user for selection, and in an embodiment in which defined archetypes are stored on archetype database 130 web browser 180 communicates with server 20 and provides to the user a list of archetypes stored in archetype database 130, accessed via user name and password. In either event, the user selects one of the defined archetypes. In one embodiment the selected archetype is then stored in memory 110 of user computing station 40 to be associated with the current browsing session, or used as the default for all future browsing sessions.

In one embodiment each archetype is encoded such that each field in the archetype is allocated a different attribute. Utilizing the non-limiting illustrative example indicated above, the archetype is in the form of: ‘age’, ‘gender’, ‘profession’, ‘hobby’, wherein each field is filled in with the user selected values. In one embodiment each user selected value has a predetermined code, with a non-selected attribute being coded with a predefined “don't care” value. In one non-limiting illustrative example, encoding of an archetype is shown in the table below, in which the first column describes the attribute type, the second column describes the position in the archetype string, the third column describes the particular attribute value, and the fourth column describes the code symbol:

Field position Attribute (from left) Value Code Age 1 13-16 a 16-18 b 18-21 c 21-31 d 31-41 e Gender 2 male m female f Profession 3 teacher a student b engineer c accountant d Hobbies 4 Rock music a1 Classical music a2 movies bx books cx Adventure books c5 In the above example, the archetype ‘age: 31-41, male, engineer, likes movies’ will be encoded as ‘emcbx’. The archetype ‘age: 31-41, male, likes movies’ will be encoded as ‘emxbx’, wherein the first ‘x’ represents “don't care”.

In another embodiment each attribute is allocated a respective pre-determined code, and each value associated with each attribute is allocated a respective pre-determined code. In yet another embodiment the archetype is left unencoded.

In one embodiment processor 70 of server 20 is further arranged to generate meta-descriptors responsive to the archetypes stored in archetype data-base 130. The generated meta-descriptors comprise attributes and values stored in attribute database 150 and the associated values stored in value listing 160, respectively, as described above in relation to generating archetypes. In one embodiment one meta-descriptor is generated for each archetype stored in archetype database 130, with the generated meta-descriptor fully corresponding to the respective archetype, i.e. including the same attributes and values as the respective archetype. In an embodiment wherein the archetype is encoded, the meta-descriptor is in one embodiment encoded in the same way. In another embodiment a plurality of meta-descriptors are generated for each archetype stored in archetype database 130, with each generated meta-descriptor corresponding to a portion of the respective archetype, i.e. a portion of the attributes and values of each meta-descriptor is the same as a portion of the attributes and values of the archetype. In the embodiment wherein the archetype is encoded, with each field of the archetype representing a different attribute, the meta-descriptor corresponding to a portion of an archetype is in one embodiment encoded in the same way, with the fields not corresponding to the specific portion of the archetype being encoded as “don't care”. In another embodiment one meta-descriptor is generated corresponding to a plurality of archetypes, wherein each attribute of the meta-descriptor may include a plurality of values. In one non-limiting illustrative example a meta-descriptor could be ‘age: 13-16, 16-18, 18-21; gender: male, female’. In all of the above embodiments each meta-descriptor is preferably then stored in meta-descriptor database 140 associated with an address of the associated object 170, as described above.

Alternatively, each meta-descriptor is stored in meta-descriptor 175 attached preferably as part of a tag associated with the respective object 170. More specifically, the meta-descriptor is chosen so as to represent the targeted population of the object 170. In one embodiment objects 170 represent a plurality of web sites, wherein a meta-descriptor is attached to each web site such that the meta-descriptor represents the targeted population of the web site. In another embodiment a meta-descriptor is attached to each web page of each web site such that the meta-descriptors represent the different targeted populations of the different pages of the web sites. In one embodiment the meta-descriptor is attached to an existing meta-data tag.

In one embodiment processor 90 is arranged to retrieve attributes from attribute database 150 and to retrieve for each retrieved attribute values from value database 160. The retrieved attributes and values represent the target population of an object 170. As described above, for each attribute there may be a plurality of values selected, as the target population may include a wide range of people. Processor 90 is further arranged to generate a meta-descriptor for the object 170 and to attach the generated meta-descriptor thereto, as described above.

In one non-limiting illustrative example a user located at user computing station 40 accesses search engine 190 in order to search for a desired object 170 accessible via network 50. In one embodiment search engine 190 compares the archetype associated with the user with the meta-descriptors attached to the plurality of objects 170 and presents the user only with objects 170 exhibiting a meta-descriptor corresponding with the user's archetype. In one embodiment the user can decide if search engine 190 should perform such filtering, or not. In another embodiment the comparing and filtering, as described above, is done by web browser 180. In one embodiment the meta-descriptor attached to an object 170 is broadcast throughout network 50, for example by broadcasting the meta-descriptor through search engines, such as search engine 190.

In the embodiment wherein network accessible host 30 is a database stored on memory 110, in one embodiment the creating of archetypes and meta-descriptors as described above is done by a computer program run on processor 120. In such an embodiment archetypes and meta-descriptors are created to facilitate quick finding of files located in a database stored on memory 110 relevant to a specific user.

FIG. 5 illustrates a high level flow chart of a method of providing targeted searching or browsing, according to an exemplary embodiment. In stage 1000 a selectable plurality of attributes are provided, preferably in a network accessible server, such as server 20 of FIGS. 1 & 2. The selectable plurality of attributes optionally comprises at least one of: age, gender, profession, residence area, income level and marital status. In one embodiment the attributes do not represent any personal information, such as: name, telephone number, or address. In one embodiment the selectable plurality of attributes are presented to a user at a user computing station, such as user computing station 40 of FIGS. 1 and 4.

In stage 1010 an input is received at the network accessible server representing a selection of one or more attributes. In one embodiment the input is responsive to a user input provided via user input device 100. In stage 1020, for each selected one of the selectable plurality of attributes of stage 1000, a selectable plurality of values are provided in the network accessible server. In one embodiment the selectable plurality of values are shown to a user at the user computing station. As described above, the term values used herein includes any word, or words, defining the different options that exist for each attribute. It is to be understood, that in the event that specific digits are allowed, each potential value which may be entered by the user is considered to be one of the selectable values.

In stage 1030 an input is received at the network accessible server representing a selection of a value for each selected attribute. In one embodiment the input is a user input provided via user input device 100. In one embodiment the selected values provide at least a partial description of the user. In stage 1040 an archetype is automatically generated, preferably in the server, responsive to the selected attributes and values of stages 1010 and 1030. In one embodiment the generated archetype is encoded with a pre-determined coding. In optional stage 1050 the generated archetype is then stored on the user computing station. In one embodiment the generated archetype is further stored on the network accessible server.

In optional stage 1060 at least a portion of the selectable plurality of attributes of stage 1000 is retrieved, preferably by network accessible host 30 of system 10 as described above in relation to FIGS. 1 and 3. In another embodiment the retrieving is done by the server 20. In optional stage 1070 at least a portion of the selectable plurality of values of stage 1020 is retrieved for each retrieved attribute of stage 1060, preferably by network accessible host 30 of system 10 as described above in relation to FIGS. 1 and 3. In another embodiment the retrieving is done by the server 20.

In optional stage 1080 a meta-descriptor is generated responsive to the retrieved attributes and values. In one embodiment the meta-descriptor is generated for an object stored on the network accessible host. In one embodiment the meta-descriptor is generated by the network accessible host, and in another embodiment the meta-descriptor is generated by the server. In one embodiment a unique meta-descriptor is generated for each generated archetype of stage 1040. In another embodiment a plurality of meta-descriptors are generated, each generated meta-descriptor corresponding to at least a portion of a generated archetype of stage 1040. In one embodiment each generated meta-descriptor is encoded with a pre-determined code, in one embodiment the pre-determined code being the same as the pre-determined code of stage 1040. In one embodiment the meta-descriptor is further generated responsive to the content of the respective object, wherein the generated meta-descriptor comprises attributes and values representing the targeted population of the object. In one embodiment a meta-descriptor is retrieved from the server, such as server 20 accessible via network 50, for an object stored on network accessible host 30.

In optional stage 1090 the generated meta-descriptor is associated as a tag of the object. In one embodiment the meta-descriptor is attached to an existing meta-data tag of the object.

Thus certain elements of the present embodiments enable a method and system for generating archetypes for users and meta-descriptors for network hosted objects, such as web sites. In one embodiment a user selects at least one attribute from a selectable plurality of attributes. The user further selects a value, from a selectable plurality of values, for each selected attribute. An archetype is then generated responsive to the selected attributes and values, and the archetype is thus representative of the user, without revealing personal identifying information. A meta-descriptor is generated responsive to the selectable plurality of attributes and associated valued and attached to a network hosted object. In one embodiment, when the user performs a search, using a search tool, only objects with an meta-descriptor corresponding to the archetype of the user are displayed to the user.
